The Wichita truck was built by the Wichita Falls Motor Company from Wichita Falls, Texas, not from Wichita, Kansas.

They started in 1911 and existed until 1932. The pictured truck with its solid tire wheels and chain drive makes me think that it was built some time around 1914/1916. Wichita built a range from 1-to to 5-ton trucks. The puzzle truck looks rather light, so I go for a 1.5-ton truck. The engines were made by Waukesha. What else do you want to know?
